There are two types of the platted holes:

a)signal PTHs between TOP and BOT sides with no connection on the Cu core

b)cooling PTHs, which are connected with the Cu core.

Soldermask Super Bright White is the most commonly used with a reflectivity of approximately 89% and other colors such as green, black, red and blue are also available.

Metal Core Printed Circuit Board MCPCB

MCPCB means the metal-based printed circuit board (MCPCB), that is, the original printed circuit board attached to a better thermal conductivity of the other metal, can improvethe heat dissipation of the circuit board.

Currently the most common MCPCB including: Aluminium PCB,Copper base PCB,Iron PCB. Aluminum PCB has good heat transferring and dissipation ability, but yet relatively cheaper; copper PCB has even better performance but relatively more expensive, and Iron PCB can be divided into normal steel and stainless steel. It more rigid than both aluminum and copper, but thermal conductivity is lower than them too. People will choose their own base/core material according to their different application.

MCPCB Prototype

To correctly cut the metal core layer without breaking the insulation,
Accuracy in depth control when cutting is essential.

When counter is routing an aluminum base, a high torque spindle motor is used.

A MCPCB prototype is produced by using machines with precisely driven
Z-axis, an accurate and ruggedized mechanism, and a flat working table.

Types of MCPCB (Metal core PCB)

Metal core PCB are sorted according to the location of the metal core and the trace layers of the PCB.

There are 5 main types of metal core PCB and these are

-Single Layer MCPCB (one trace layer on one side),
-COB LED PCB (one trace layer),
-Double Layers MCPCB (two trace layers on one side),
-Double Sided MCPCB (two trace layers on both sides) and
-Multi Layers MCPCB (More than two trace layers on every board).

MCPCB Benefits VS FR4 PCB

Thermal expansion and contraction is the common nature of the substance, different CTE is different in thermal expansion. As its own characterics, aluminum and copper have unique advance than normal FR4, thermal conductivity can be 0.8~3.0 W/c.K.

Flatness maintained in all 3 layers

High Heat Dissipation

High density of components

Reduced PCB size / Small footprint

It is clear that the size of the metal-based printed circuit board more stable than insulating materials. The size change of 2.5 ~ 3.0% when Aluminum PCB and aluminum sandwich panels was heated from 30 ℃ to 140 ~ 150 ℃.

Components operate at lower temperatures

Durable

Higher Watt Density

Longer component life

Less hardware (topical heat sinks, screws, clips, etc)

Lower Manufacturing Cost

Selective dielectric removal can be used to expose inner-layer and or the baseplate for component attachment to these layers which also reduces thermal resistance.

Chip On Board Metal Core CB

MCPCB is used in thermoelectric separation application Th e Micro-chip or die is directly in touch with the metal core where the heat dissipate. And electrically interconnect the trace of circuit board (wire bonding) so thermal conductivity of COB MCPCB is more than 200 W/m.k.
